"I generally really dislike leaving feedback. I find myself honest to a fault because I believe it's a responsibility to leave honest, accurate feedback for potential other customers. Then I go through this process of "am I being too nit-picky", "am I being overly sensitive", etc, and finally I don't leave the review because if it isn't good, will it hurt the business, or just as bad, reviews that say "they were great" isn't helpful at all....and so I buckle under the pressure of my own assessment. I say all that here to tell you I have ZERO issues writing this review right now. I reached out to Mr. Electric because a project that was supposed to start in August was bumped up on the schedule, and as always, I procrastinated getting someone to come out and move an electrical box and some conduit. I reached out to Mr. Electric on a Thursday, and the following Monday was promised someone (Travis M from Mr Electric) would come out and give us a quote on the work. Travis showed up right on time, and only was he super-flexible with whatever work I asked for (added in 2 outside electrical boxes besides the electrical box reconfiguration and move), they gave me a more than reasonable quote for the work and told me they could get the work done right then and there. My wife and I agreed, and the final result was phenomenal. Travis M and also Andrew from Mr. E jumped right in, and did a superb, professional job in a matter of a couple of hours. I would be remiss if I didn't say that not only was their work professional, their attitude and conduct was professional beyond reproach. To be fully honest, they looked and acted the part of professional electricians from a professional company. These 2 gentlemen represented Mr. Electric in a fully excellent way, and they will be my go-to for future projects. Perfect 10 out of a possible 5 stars!"

"The service provided by Shawn of Eason electric was exceptional. He worked hard to solve 2 challenging projects at my home. I appreciated that he took the time to explain what he was going to do in detail and that he always arrived when he said he would. My ceiling fan and new outdoor receptacles are wonderful upgrades! I would not hesitate to hire Shawn again!"

"Kevin did excellent work replacing an outdoor cable wire, obtaining a permit on my behalf from the local township and coordinating the work with the municipality and electricity supplier. He was thorough, knowledgeable and diligent and extremely patient despite the poor communication from the electricity supplier and crew. Kevin also made safe several outlets after mold remediation and a few others that he noticed requiring rewiring. Kevinâ s work and professionalism is exceptional and I highly recommend his services and will hire him again."

Electrical questions, answered by experts

Technically, an outdoor outlet can be on the same circuit as an indoor outlet, but it's generally not recommended. Outdoor outlets should ideally be on a dedicated circuit that doesn't share power with other indoor or outdoor outlets. This helps ensure that the outdoor outlets are able to handle the additional electrical load without overloading the circuit. Additionally, outdoor outlets are often exposed to the elements, which can increase the risk of electrical shock and other hazards. If you must have an outdoor outlet on the same circuit as an indoor outlet, be sure that the circuit has the capacity to handle the additional load.

It prevents electrical surges, protects your home from things like electrical fires, and prevents you from getting shocked if an errant surge runs through your power line. Without grounded wires, your appliances could also get damaged during lightning storms.

No, not all thermostats require a C-wire. Older manual and programmable thermostats typically do not need one. While many smart thermostats do require a C-wire to function correctly, some models can operate without one, often at the expense of certain features. A C-wire provides a constant source of power, which enables the thermostat to stay connected to Wi-Fi and keep its display screen lit on-demand. If you are upgrading from an older thermostat to a smart model that requires a C-wire, you may need to install one first for it to work as intended.

Yes, a whole-house surge protector needs a designated breaker in your electrical panel. You will need to choose a double pole breaker that has two wire terminals so that your surge protector can connect to the breaker. This breaker needs two breaker slots inside of your panel. If you do not have room, then you will either need to adjust some of the existing breakers in the panel box or hire an electrician to install a subpanel.

The standard copper wire gauge to use with any 30-amp circuit is a 10-gauge wire. The National Electric Code specifies a 10-gauge wire with appliances like water heaters running on 30 amps. If you try to use a smaller gauge wire, such as a 12 gauge, with a 30-amp breaker, you run the risk of the wire overheating and melting or causing a fire. Because of the safety hazards, the gauge of the wire is not an area to try to cut costs when connecting a 30-amp breaker to a water heater.
